“随机爆发”理论最近被提出来解释牙周病进展的模式。该理论预测，个别部位骨丢失的进展不依赖于先前的骨丢失和年龄。设计了一项纵向放射学研究来验证这一假设，并描述了一组180名未接受系统牙周治疗的受试者（18-68岁）在2年内骨水平的变化。结果表明，94%的部位在观察期内牙槽骨水平没有明显变化。总人口的平均年骨丢失为0.11 mm。通过对年龄的纵向骨丢失进行回归，结果表明，33至56岁之间的骨丢失率迅速增加，而18-32岁和57-68岁的年龄段显示出不同的模式。此外，骨丢失率随着初始骨丢失的增加而增加。这一点在年龄最大的群体中不太明显。得出的结论是，本材料中骨丢失的进展与“爆裂”理论一致。然而，这种进展并不是随机发生的，与以前的牙槽骨和时间损失有关。
The "random burst" theory has recently been proposed as an explanation of the pattern of periodontal disease progression. The theory predicts that the progression of bone loss at individual sites is not dependent upon previous bone loss and age. A longitudinal radiographic study was designed to test this hypothesis, and to describe the changes in bone level over 2 years in a group of 180 subjects (18-68 years of age) who were not under systematic periodontal treatment. The results indicated that 94% of the sites did not show significant changes in the alveolar bone level during the observation period. The mean annual bone loss for the total population was 0.11 mm. By regressing longitudinal bone loss upon age, it was shown that the rate of bone loss increased rapidly between 33 and 56 years of age while a different pattern was shown for the age intervals 18-32 and 57-68 years. Also, the rate of bone loss increased with increasing initial bone loss. This was less evident in the oldest age group. It was concluded that the progression of bone loss in the present material is consistent with a "burst" theory. However, the progress did not occur randomly with regard to previous loss of alveolar bone and time.
